Sensory cells and sensory neurons allow multicellular animals to sense physical and chemical cues from their environment. what k
Lynna [10]
The options for this question are:
A. Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
B. All sensory cells and sensory neurons fire action potentials when they bind a signaling molecule.
C. Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.
 The best answer choices are: A & C
Sensory cells and sensory neurons have electrically excitable membranes that change in charge potential in response to binding an environmental signaling molecule.
Sensory cells and sensory neurons have protein receptors linked to intracellular or membrane-based signaling pathways that alter ion channel permeability.

Explanation:
Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses.
For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Sensory receptors located in the dermis or epidermises of the skin are called cutaneous receptors. These include nociceptors and thermoreceptors. <span>

Eukaryotic cells tend to be 10-1,000 times larger than prokaryotic cells, which it means that it takes much longer for molecules
ELEN [110]

Answer:

The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.

Slower

Explanation:

Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.

In 1838 botanist Matthias Schleiden determined that all plants are composed of cells. In 1839 anatomist Theodor Schwann proposed
TiliK225 [7]

Answer:

This question lacks options, the options are;

A. All cells have a cell wall.

B. All cells arise from pre-existing cells.

C. All cells are capable of photoshynthesis.

D. All cells can develop into any other type of cell.

The answer is B.

Explanation:

The widely accepted universal cell theory is known to be contributed to by three scientists viz: Matthias Schleiden, Theodor Schwann and Rudolph Virchow.

As rightly stated in this question, Botanist Mathias Schleiden and Zoologist Theodor Schwann proposed that plants and animals are made up of cells in the year 1838 and 1839 respectively. However, in 1855, biologist Rudolph Virchow expanded the cell theory by adding that all living things are composed of cells and that these cells arise from pre-existing cells.

The collaboration of these three scientists brought about the cell theory that states:

* Cells are the basic unit of all living things.

* All living things are made up of one or more cells.

* All cells arise from pre-existing cells.

Bones kept in hydrochloric acid becomes soft why?
DanielleElmas [232]

Bones are made up of Calcium Phosphate given by the chemical formula, Ca_{3}(PO_4)_2. When bones are kept in Hydrochloric acid, given by the chemical formula, HCl, they become soft because the calcium compound present in the bones changes its form. The following double displacement reaction takes place when the bones are kept in HCl,

Ca_{3}(PO_{4})_{2} + HCl ---> CaCl_{2} + H_{3}PO_{4}

Calcium chloride is water soluble, and gets washed away. This makes the bone thin and soft.
